modularandroid's Introduction

ModularAndroid

An Android test project to implement Modular approach to build structure

Create modules

Create a module
If the module has any Dagger, implement it into main module also.

The env file is in gradle.properties:

Eg : apiUrl=http://github.com/
Implement those into the module by

//Get env from gradle properties
 def API_URL = System.getenv("API_URL") ?: apiUrl

 android.buildTypes.each { type ->
     type.buildConfigField "String", "API_URL", "\"$API_URL\""
 }

where API_URL is the key in gradle.properties.

Build the module.
Include the module into main module's gradle:

        dependencies{
    		implementation project(':moduleName')
    	}

For Dagger DI, you'll need to add a Module class that impliments all the dagger module classes like Singleton, Providers into one class. Like so:

        @Module
        class SomeClass{
            @Provides
            @Singleton
            fun provideUrl():String{
                return BuildConfig.URL
            }
        }

Implementing Module

After creating and implementing modules into main module.
For Dagger, you'll need to add those DaggerModule class into the AppComponent.kt class of the main module.

        @Singleton
        @Component(modules = [(AndroidInjectionModule::class), (AppModule::class),(NetworkModule::class), (ActivityBuilder::class), (ViewModelFactoryModules::class)])
        interface AppComponent {

        @Component.Builder
        interface Builder{
            @BindsInstance
            fun application(application: Application): Builder

            fun build(): AppComponent

        }
        fun inject(app: ModularAndroidApplication)
}
